Staghorn Sumac


=Habitat and Range.=--In widely varying soils and localities; river

banks, rocky slopes to an altitude of 2000 feet, cellar-holes and waste

places generally, often forming copses.



From Nova Scotia to Lake Huron.



Common throughout New England.



South to Georgia; west to Minnesota and Missouri.



=Habit.=--A shrub, or small tree, rarely exceeding 25 feet in h
ight;

trunk 8-10 inches in diameter; branches straggling, thickish, mostly

crooked when old; branchlets forked, straight, often killed at the tips

several inches by the frost; head very open, irregular, characterized by

its velvety shoots, ample, elegant foliage, turning in early autumn to

rich yellows and reds, and by its beautiful, soft-looking crimson cones.



=Bark.=--Bark of trunk light brown, mottled with gray, becoming dark

brownish-gray and more or less rough-scaly in old trees; the season's

shoots densely covered with velvety hairs, like the young horns of deer

(giving rise to the common name), the pubescence disappearing after two

or three years; the extremities dotted with minute orange spots which

enlarge laterally in successive seasons, giving a roughish feeling to

the branches.



=Winter Buds and Leaves.=--Buds roundish, obtuse, densely covered with

tawny wool, sunk within a large leaf-scar. Leaves pinnately compound,

1-2 feet long; stalk hairy, reddish above, enlarged at base covering the

axillary bud; leaflets 11-31, mostly in opposite pairs, the middle pair

longest, nearly sessile except the odd one, 2-4 inches long; dark green

above, light and often downy beneath; outline narrow to broad-oblong or

broad-lanceolate, usually serrate, rarely laciniate, long-pointed,

slightly heart-shaped or rounded at base; stipules none.



=Inflorescence.=--June to July. Flowers in dense terminal, thyrsoid

panicles, often a foot in length and 5-6 inches wide; sterile and

fertile mostly on separate trees, but sterile, fertile, and perfect

occasionally on the same tree; calyx small, the 5 hairy,

ovate-lanceolate sepals united at the base and, in sterile flowers,

about half the length of the usually recurved petals; stamens 5,

somewhat exserted; ovary abortive, smooth; in the fertile flowers the

sepals are nearly as long as the upright petals; stamens short; ovary

pubescent, 1-celled, with 3 short styles and 3 spreading stigmas.



=Fruit.=--In compound terminal panicles, 6-10 or 12 inches long, made up

of small, dryish, smooth-stoned drupes densely covered with acid,

crimson hairs, persistent till spring.



=Horticultural Value.=--Hardy throughout New England. Grows in any

well-drained soil, but prefers a deep, rich loam. The vigorous growth,

bold, handsome foliage, and freedom from disease make it desirable for

landscape plantations. It spreads rapidly from suckers, a single plant

becoming in a few years the center of a broad-spreading group. Seldom

obtainable in nurseries, but collected plants transplant easily.



The cut-leaved form is cultivated in nurseries for the sake of its

exceedingly graceful and delicate foliage.
